BUTTON.

Specification of Letters Patent.

Patented May 13, 1919.

Application flied December 29, 1917. Serial No. 209,396.

To all whom it may concern:

Be it known that we, LLOYD A. ANGLE and J oi-IN P. SAGER, citizens ofthe United States, and residents of Rochester, in the county of Monroeand State of New York, have invented certain new and useful Improvementsin Buttons, of which the following is a specification.

The present invention relates to buttons, and more particularly to thetype in which the button body is formed prior to the connection of theshank thereto, and has the shank secured to it by a bendable anchoringportion deflected into an undercut pocketed portion in the button body,an object of this invention being to provide cooperating portions on theshank and the button body whereby lateral strain on the anchoringportion of the shank is reduced to a minimum.

To this and other ends the invention consists of certain parts andcombinations of parts all of which will be hereinafter described, thenovel features being pointed out in the appended claims.

In the drawings E Figure 1 is an enlarged axial section through a buttonconstructed in accordance with this invention; l w I Fig. 2 is asectional view through the button body;

Fig. 3 is a plan view of the rear face of the button body;

Fig. 4 is a sectional view through the shank;

Fig. 5 is a perspective view of the shank;

Fig. 6 is a detail View of the shank showing it milled or roughened toprevent turning in the button body; ;..,Fig. 7 is a detail view insection of an embodiment in which the body is made of a substance whichwill absorb moisture;

Fig. 8 is a detached side view of an embodiment in which the shank ismade of two parts; and I Fig. 9 shows the assembled parts of the shankillustrated in Fig. 8.

Referri more particularly to the drawings, 1 indlcates a button bodymade from ,pvegetable ivory, pearl, dr the like, andhaving in its rearface a pocket..which has an undercut inner portion 2 andan outer portin3 of smaller diameter than the undercut portion with its wallsperpendicular to the plane of the button body. In this instance,

the walls of the outer portion are cylindrical and the bottom wall ofthe pocket indicated at 4 is convex.

The shank, which is separately illustrated in Figs. 4 and 5, embodies aportion which may be of any form to permit the attachment of the button,and also embodies the anchoring portion 6 which, before being introducedin the button, is in the form of a flaring cup. Between the anchoringportion and the eye portion 5 is a portion 7 which cooperates with thewall of the outer portion of the pocket in the button in order to givelateral support to the shank to take the strain off the anchoringportion after the latter has been anchored in the button. The shank ispreferably formed from a single piece of material, and the anchoringortion thereof is relatively thinner to ben easily, being separated fromthe supporting portion 7 by an annular groove 8. If desired, thesupporting portion 7 and the anchoring portion 6 may have theirperipheries roughened Ior milled to prevent all possibility of rotationbetween the shank and the button body, as shown at 9 in Fig. 6.

In uniting the shank and the button body, the button body is preferablysupported externally and the shank is introduced into the pocket andforce is exerted thereon to bend or spread the anchoring portion 6, sothat said portion enters the undercut portion 2 of the pocket in themanner shown in Fig. 1, the convex bottom 4: facilitating thisspreading. While the shank before being connected to the body of thebutton has the diameter of its anchoring portion substantially the sameas that of the supporting portion 7, the spreading tends to increase thediameter of the anchoring portion so that the shank will be held in thepocket. The walls of the supporting portion 7 be ing the same as that ofthe outer wall 3 of the pocket, in this instance, cylindrical, saidwalls provide cooperating portions which will reduce the lateral strainson the anchoring portion 6 to a minimum.

In Fig. 7 is shown an embodiment of the will absorb moisture. The outerportion 3 of the button body may also be slightly A larger than thecylindrical portion 7 of the shank. a In Figs. 8 and 9. is shown anembodlment in which the shank is made of two parts. One of these partsis in the form of a piece of wire bent into an eye with its endsextended in one direction and parallel, the outer faces of said endsbeing roughened at 5". The other part comprises a body having acylindrical portion 7 and a flaring an- 'choring portion 6 separatedfrom the supbody in the same manner as the other emfbodiment.

What we claim as our invention and desire to secure by Letters Patentis 1. A button comprising a body portion formed with a pocket in itsrear face, said pocket having anundercut portion and a cylindricallyformed wall extending from said undercut portion to the rear face of thebutton, the diameter of the outer por- 1,sos,2ae

undercut portion of the pocket, said cylin-- drical portion fitting thecylindrical wall of the pocket, the portions of the shank connectlng theeye portion and the cylindrical portion being less in diameter than thecylindrical' portion.

2. A button comprising a body portion formed With a pocket in its rearface, said pocket having an undercut portion and a cylindrically formedwall extending from said undercut portion to the rear face of thebutton, and a shank formed of a wire portion provided with an eye andtwo ends, and an anchoring portion projecting into the undercut portionand having a cylindrically formed portion fitting :the cylindricallyformed Wall of the pocket, the cylindrically formed portion receivingthe ends of the wire portion.
